I'm going to cut my wetsuit

I picked up a sleeveless suit at one of the Vegas Goodwill stores for a whopping $12. Really hard to beat that deal. I didn’t want to go off and spend big bucks on a suit I might only wear a couple dozen times (I have other suits). Fits really well except for the legs are too long. I want to trim off maybe 6-8" off the bottom of the legs. Even though I don’t expect this to get a whole lot of regular use, is there anything I should or could do to protect the cut ends?

Some suits have a backing in the legs/arms specifically to cut to size. Try to stay in that zone if it’s present.
Otherwise try to make a really clean cut with no nicks that can tear later. It help to make a few practice cuts before cutting to where you want it. Really sharp scissors or an Xacto knife is the way to go.

Thanks for the reply. I looked but mine did not have any kind of marks to indicate where it would be safe to cut. Honestly, I just “eyeballed” it and started off a little shorter than I thought I would need. I figured cut it, try, cut some more. I’ve learned from far too many mistakes about cutting too much too soon. I ended up cutting just about 4" off, tried it on and it was damn near perfect. I’m sure I could go a couple inches shorter but probably won’t only because of some logo text on the legs. I may be cheap but I’m also a little bit obsessive about such things.

Do the seams not fray, if they are not taped?

I want to cut the arms of my wetsuit as they are too long. Can’t decide if I should do it myself or get it done professionally (cost and sending it off are a pain in the butt). The arm seams are not pre-taped for cutting. I wonder if I put tenacious tape over the seam and then cut the arms, will that work ok?

I chopped mine with scissors looks really unprofessional but has worked fine for years.

Tenacious Tape is probably not the best choice, Seam Grip would be the better choice (it’s also used to repair wetsuits and dry suits).

It’s very easy to DIY, especially if you know how to threw a few stitches then Seam Grip it.

I’ve cut my down to capris, to make it easier to get off. I used a sewing wheel cutter, should be easy to find a craft store, and a straight edge. This works for clean edges. For $12 if it lasts for a couple seasons before fraying, money well spent. I’m on my second season with mine and no issues, yet.
